Red-and-white Spinetail
Certhiaxis mustelinus
Strikingly bicolored spinetail, bright rusty above and white below. Note the dusky lores. Found in riverine marshes. The song is a loud rattle: “tch-t-t-t-t-t-t-t-t-t-t-t-t-t.”. The similar Yellow-chinned Spinetail has a pale eyebrow and a yellow chin and lacks the dusky lores; its song is similar but drier.
识别特征
The red-and-white spinetail is 14 to 15 cm (5.5 to 5.9 in) long and weighs 14 to 16 g (0.49 to 0.56 oz). The sexes have the same plumage. Adults have black lores and a dusky brown line through the eye on an otherwise reddish brown face. Their crown and back are also reddish brown, with the back being slightly lighter. Their rump is a paler rufescent brown. Their wings are mostly bright rufous with dark fuscous tips on the flight feathers. Their tail is mostly rufous with duller brown inner webs on the central pair of feathers; the feathers have few barbs on their ends giving a spiny appearance. Their chin and throat are white. Their underparts are white with a pale buff wash on the belly, flanks, and undertail coverts. Their iris is brown, their maxilla gray to blackish, their mandible dark gray, and their legs and feet light gray. Juveniles have less uniform rufous upperparts than adults, with a dusky crown and some faint mottling on the breast.

分布与栖息地
The red-and-white spinetail is found along river corridors in the central Amazon Basin, mostly in Brazil but also in extreme southeastern Colombia and in northeastern Peru. The major rivers are Peru's Ucayali and Brazil's Madeira, Juruá, Purús, and the Amazon itself to the Atlantic Ocean. It primarily inhabits freshwater marshes, especially those around old river islands where there is a mix of bushes, grasses, and emergent vegetation. In its small Colombian range it occurs very locally in seasonally flooded grasslands. In elevation it ranges from near sea level to 150 m (500 ft).

行为
The red-and-white spinetail is essentially resident throughout its range, though it probably makes local movements from flooded islands during the rainy season.<p>The red-and-white spinetail feeds on arthropods. It forages singly and in pairs, gleaning prey from foliage and small branches close to the ground.<p>The red-and-white spinetail is thought to be monogamous. Its nest is a ball of thorny sticks built in low vegetation over water. Nothing else is known about its breeding biology.<p>The red-and-white spinetail's song is a "loud, dry, irregularly undulating rattle": "tch-t-t-t-t-t-t-t-t-t-t-t-t-t". Its call is "chuk-cheh" or "chuck-chuck-chuck".

Yellow-eyed Black-Flycatcher
Melaenornis ardesiacus
Slim, long-tailed, all-black flycatcher with a pale yellow eye. Found along the edge and in clearings within Albertine Rift montane forest. Single birds of pairs perch out on conspicuous perches, sometimes quite low. Calls include low chuckling notes and a high, thin whistle; the song is a whispy, complex mix of high-pitched notes. Distinguished from all similar black birds by its pale eye.
Sulawesi Serpent-Eagle
Spilornis rufipectus
A large, broad-winged dark raptor. Adults show a short crest, a blackish head with yellow facial skin, a chocolate-brown back, and rust-colored underparts with extensive white speckling. In flight appears blackish with a conspicuous single broad white bar on the rear of the wings and tail. Immatures pale, with dark mask, boldly streaked underparts, and dark chocolate upperside. In flight, note extensive dark markings on underwings. Inhabits forests, edges, rice paddies, and sparsely wooded areas from lowlands to mountains. Confined to Sulawesi and the Banggai and Sula Islands. Speckled rusty underside identifies perched adults, dark mask perched immatures. In flight, distinguished from all other local raptors by white bar on rear wing and tail of adults, and by bold streaking below in immatures. Gives strident “kew” calls, sometimes with inflection: “kew-di-lew.”
Guayaquil Woodpecker
Campephilus gayaquilensis
Large woodpecker found in both dry and humid forest in western Ecuador, northwestern Peru, and far southwestern Colombia. Note red head, white “V” on black back, white neck stripes, and barred lower underparts. On female, white neck stripe extends to beak. Similar to Lineated Woodpecker, but Guyaquil Woodpecker’s back stripes converge in a “V”, and it lacks a dark mask around the eye. Often perches on dead trees, and periodically pounds out a loud, powerful burst of knocks.
